Introduction

Olaf the Berserker - Plain and Simple -
This is the plain and simple version for newbies buying Olaf the Berserker. He is a new Tank DPS champion and to be frank this is the only viable way to play him due to his spells. You could mess with a Infinity Edge, Starks build and go straight DPS but you throw vicious strikes right out of the window for viability.

Masteries + Runes

Masteries:

I run a 9/21/0 build basically get Archaic Knowledge and the typical Defensive Talents.

Summoner Abilities

I take Exhaust and Ghost however you could use Ghost and Ignite...w/e you find more effective for your play style. Exhaust will allow you to catch someone if they have merc treads and your frozen mallet falls off for that last hit / kill strike. Ignite will kill steal and get you a little more gold.

Items

Items:

Olaf is a Tank DPS character 100% there is no other discussion about it...his build should be Tankish very Mordekaiser on TT style:

Skilling Order

Skill Order:

This is literally the hardest part because mathematically Vicious Strikes is crap compared to the other 2 which are burst. Undertow is also your farming spell throw it down a line of minions and collect gold. So it has a benefit for leveling. But to be honest I've found that Reckless Swing is your champion killer. This does just about as much as Garen's Ultimate (Yey garen is a crap champ) And does very little dmg to you it may sound bad on paper but it really isn't much ingame. You can build it back up with Vicious Strike easily. To be honest i've been rotating my skill order a lot just trying out different stuff early on.

To be honest start with Vicious Strikes then in the next 2 levels get your Q and E so you have all 3 at your disposal. Then depending on who is against you in a lane start building up what you feel is best...so like this:
